Based on your friend's message, there are **3 babies** β but they're not human babies, they're **kittens**! π± Here's the translation of what she said: *"Omg!! Did you catch what Lisa shared on Insta? Her cat had 3 babies β the little ones look soooo cute. I want a cat too :((("* So a few things to clarify: - **"Tatze"** literally means "paw," but here it's being used as an affectionate nickname for Lisa's **cat**. - **"3 Junge"** means "3 young ones" (offspring) β in this context, 3 kittens. - Your friend isn't announcing her *own* babies β she's excitedly telling you about **Lisa's cat** having kittens, and saying she wants a cat too. So if you were planning to congratulate your friend on *her* new babies, you might want to hold off! π The kittens belong to Lisa. You could instead reply something like sharing in the excitement about the cute kittens, or tease your friend about wanting a cat of her own.
